The best way to prove this to your boss is with a trial period that has defined goals. In general, a great employee in the office will be a great employee at home. So propose benchmarks.
If your employer were to allow you to work from home one day a week, or leave an hour earlier to reduce your time in the office, or to use hourly vacation or any of the other flexibility programs, how would the success of this benefit be measured? Make sure you both agree on the goals and the methods of continuous communication.
Take small steps and don't expect overnight miracles. Offer to work from home just one or two days a week to start, and suggest a three-month trial period before pressing the boss for a permanent change. If the arrangement works well, your boss will see the benefits.
Remember -- if you want it to work, you can't use the "I didn't know" excuse because you weren't in the office. You have to actively make sure that nothing falls through the cracks. Accept the responsibility for communication and performance. This will build trust between you and your boss and co-workers.
